InMotion WS710925 Drive Axle Shaft Seal - Front Outer

Drive Axle Shaft Seal Overview

The InMotion WS710925 is a drive axle shaft seal built to create a secure barrier against contaminants and fluid loss. It is specified for front outer applications on select Ford Super Duty trucks and the Ford Excursion, with hand-install style fitment noted in the catalog data.

Key Features

• Polyacrylate construction for sealing performance in demanding driveline service.
• Helps block debris and moisture from reaching sensitive differential components.
• Supports leak control to help maintain differential protection.
• Cataloged for front outer fitment on Ford heavy-duty truck applications.
• Part number WS710925 for easy identification and ordering.

Detailed Description

WS710925 is engineered as a differential pinion seal for applications where a tight, reliable seal is needed around the driveline assembly. The listed dimensions include a 5.479-inch outside diameter, 3.545-inch shaft diameter, 5.465-inch housing bore, and 0.646-inch width, which are important reference points when matching the seal to the housing and shaft interface. This seal is used on Ford F-250 Super Duty, Ford F-350 Super Duty, Ford F-450 Super Duty, Ford F-550 Super Duty, and Ford Excursion applications shown in the fitment data.

For buyers searching for a Ford F-250 Super Duty front outer seal or a Ford Excursion driveline seal, WS710925 provides a direct replacement option for the listed applications. The design focuses on keeping contaminants out and helping preserve differential life under road and off-road use. The part number WS710925 is also useful when verifying the correct seal against service records or catalog listings.

What It Helps Address

• Fluid seepage at the differential pinion area.
• Contamination from dirt, dust, and moisture.
• Wear risk caused by compromised sealing surfaces.
• Loss of sealing integrity in driveline service.
• Fitment confusion when replacing a front outer axle seal.

Installation Notes

Fitment data lists hand-install style applications, so careful alignment during installation is important. Verify shaft diameter, housing bore, and outside diameter before installation, and confirm the vehicle application against the catalog listing for the correct Ford Super Duty or Ford Excursion configuration.
